To all whom it may concern:

Be it known that 1, JARVIS CASE, of WashingtonOourt-House, in the county of Fayette and State of' Ohio, have invented certain Improvements in Two-Row Corn-Planters, of which the following is a specification:

The object of my invention is toproduce a simple and efficient planter, which may be readily converted into a cultivator bysubstituting ordinary cultivator-beams in place of the planting devices; and to this end the invention consists in various details of construction, but more especially in the peculiar construction of the main frame.

Figure 1 represents a top-plan view of the planter; Fig. 2, a longitudinal vertical section of the same; Fig. 3,a vertical section of the main frame on the line :10 00; Fig. 4, asection of the same on the line 3 3 Fig. 5, a vertical section through one end of the frame on the line az; Fig. 6, a perspective vieW,show-ing the construction of the feeding mechanism; Fig. 7, a view showing the construction of the adjustable arms or brackets of the main frame.

The machine consists, primarily, of two main parts-a front-wheeled draft-frame, A, and a rear frame, B, provided with the runners', hoppers, and all the other planting de vices, connected to the front frame in such manner that it may be readily detached to permit the substitution of cultivator-beams in its place.

- The main frame consists, essentially, of two parallel transverse iron bars, a a, arranged at some distance apart, and having their ends bent downward and united in two metal or draftspole, j, which-may consist of a single straiglitbar, as shown in the drawing, orof two diverging bars, as commonly used in 'walking-cultivators. To the under side of the tongue, in advance'of the frame, there is pivoted a transverse equalizingbar, to the ends of which there are pivoted downwardlyextending bars, f, which latter have their lower ends jointed to the ends of links g, extending backward, and hooking at their rear "ends through ears on' the axle-blocks b, as shown in Figs. Land 2.. The bars f areprovided with 'a' series ofholes, which admit of the single-trees being attached-thereto at different heights.

As a means of attaching and drawing the planter-frame B or the cultivatorbeanlsfthe mainframe is provided with' two depending arms or brackets, 0, each consisting of an eye orsock'et provided with two upwardly-diverging arms, h, the upper ends i -off which are clamped fast to the bars a a, respectively, as

shown, the parts being so arranged thatthe brackets may be adjusted laterally on the frame, and that the eyes at their lower ends are always maintained in line with the axis of the wheels, so that therocking or tilting of the frame has no effect upon the position, of the eyes, and strain received by the latter has no tendency to tip'the frame. 7

The form and construction of the brackets may be varied, provided the above-mentioned peculiarities are retained. Their upper ends may be drawn against one side of the bars 'a a by means of bolts passing through plates or washers on, the opposite side, as shown 'in the drawings, or hook-bolts used, or the ends of the arms carried around the bars and tigh tened upon themselves by bolts. The eye at the lower endsmay be aseparate piece bolted to the arms, or it may be forgedor'cazstin one piece therewith. p

To the lower end'of each'bracket I connect, by means of a horizontal pivot-bolt, l, a plate or clevis, m, to receive the arms a of the planter-frame', or in their stead the ends ofthe cultivator-beams.- The planter-frame consistsof'tworunners, 0, of the form generally used in corn-planting machines, connected at'their forward'endsby a crossbar, p, and at their rear ends by asecond and heavier bar, r,-which latter also sustains the two seed-hoppers ,s, from which' tlie seed is dropped by the feeding devices through the heels of the runners. The two bars'or arms n, preferably'made of elastic; steel, are secured at their rear ends by bolts 'to' the under side of the bar r,and extended thence forward through two loops or guides,'u, on the theordina'ry forms; but the construction represented in Figs. 2 and 6, and in the left-hand hopper in Fig. 1, is considered better than any other. A rectangular base plate or frame, 0", to sustain the hopperisformed witha groove,'d, in one side to receive and guide the feed-slide c, with 'a hole, f, to permit the passage of the seed down into' the runner below, and with a slot, g, to guide the end of an arm, 72/, which latter "serves to actuate the usual flip-valve locatedv in the runner. The feedslide c is simply a' straight bar provided with two holes or cells, 5, and'with the two inclined depressionsj. At one end the slide is bolted to the arm h, which is'in turn bolted to a bar, k, which latter extends across the machine from one feed mechanism to the other, an d receives motion from a hand-lever, l, to be operated bya boy, as usual. i Owing to the fact'that the feed-slide is of the straightand regular form, it may be drawn out after unbolting its end, and replaced by another, without removingor disturbing any of the other parts.

The bottom of the hopper above the feedslide, which is located at one side, is formed by a single plate of metal, m, inclining downward toward the slide, but cut away in such manner that the seedmay rest upon the whole slide, except at the middle of the hopper, where the metal bottom has a pointor cutoff, at, extending across the slide directly over the hole fin the under frame or plate.

The cut-off.n, which is cast upon the'bottom plate, has secured to its under side a block of soft-leather, 0. As the feed-slide moves to and fro, the two cells i pass alternately under the cut-off, carrying the grain thereunder, and discharging it, through the hole f, into the runner in the ordinary manner. a

The arm h has its free end provided with a hook or lip, to enter the before-mentioned guiding-slot g, and also has on its under side a notched stud, which engages upon and operates a lip, 10, on the upper end of the flipvalve. v 1

" For thepurpose of giving the runners the required position, and governing the depth to which they enter'the ground, and also to cover the corn in the furrows, a roller, 1", is mounted in vertically-adjustable arms directly behind each runner.

The planter-frame is provided'with a rigid arm, s, extending backward, as shown, as a means by which to lift the runners wh enrequired. 1;.

For the purpose of suspending the runners out of the ground when moving the machine to or from the field, the arm 8 of the rear frame is provided with a metal strap or arm, t, extending upwardthrough-a notched block, u, on the rear end of the main tongue, and provided with a beveled block, to, which engages automatically with the block a when the frame is raised.

The seat for the dropper is formed by extending a board from onehopper to the other, and'steps to aid the dropper in mounting are formed by extending the ends of the draft or coupling-arms n backward, as shown. Y

The drivers seat E is provided with two supporting-legs, seated in holes in blocks of i wood boltedto the sides of the tongue j of the main frame, as shown, the descent of the legs being prevented by a pin, w, connecting them and resting upon the tongue. A series of the holes for the legs are provided in order that the seat may be shifted forward and backward, and, if desired, a series of pin-holes may be made in the legs to admit of the seat being adjusted in height.

Referring back again to the main frame, I will now explain more in detail the construc tion of its sides.

The bars a a have their converging ends or arms passed down through the block I) too near each other to admit the journal 0 between them, and therefore have their adjacent faces notched or cut away to receive it. When the journal is driven home between the bars thus notched it serves'as a key and fastens them firmly in the block, preventing them from moving up or down, and also preventing the block from turning or working under the strain exerted upon the journal by thewheels. At its inner end the journal is enlarged or headed. to prevent it from passing outward through the-block; and it is prevented from turning or sliding'inward by a key or pin, y, passedthrough it and seated in a groove in the outer face of the block b, as shown. The key y is provided with a shoulder or projec= tion, over and under which'the hub of the wheel engages, as shown in Fig. 5, thereby holding the key in place.

For the purpose of marking the ground I provide the machine with a shifting or change. able marker, F, consisting of an arm having its inner end provided with a hook engaging in an eye on the frame, and its-outerendprovided with a runner, and drawn forward by means of a cord, having a hook to engage in an eye or ring on the linchpin or axle of the main wheel. When required,the marker may be detached from one side of the machine and applied to the other. Thecord, as shown, is attached to the runner-by a ring sliding on a rod on the runner, so that the cord may shift from end to end of the'runner, as required.

. Havingthus described my invention,what I claimisw 1. In combination with the arched bars a or, blocks 12, journal 0, and wheels (1, the rigid depending laterally-adjustable brackets G attached to the two bars, and provided at their lower ends with eyes or sockets-in line with the journals 0, as shown.

2. The arched draft-frame havingthe two supportingwheels, a tongue, and two rigid depending laterally-adjustable brackets, 0,
